For the meringues:
- 1⁄2 cup egg whites (3 to 4 eggs)
- Pinch of salt
- 1 tsp. fresh lemon juice
- 1 cup sugar
- 1/2 cup water
- 2⁄3 cup sugar
- 3 or 4 firm Simka or Santa Rosa plums, halved,
pitted and each half cut into 8 slices
- Pinch of salt
- 6 Tbs. (3/4 stick) unsalted butter, at room
temperature, cut into 1⁄4-inch cubes
To make the meringues, in the bowl of an electric mixer fitted with the whisk attachment, combine the egg whites, salt and lemon juice. Beat on high speed until the large, foamy bubbles become small, about 2 minutes. Reduce the speed to low and gradually add the 1 cup sugar while continuing to beat. Increase the speed to high and beat until the whites are firm and glossy, about 8 minutes.
Using a spring-loaded ice cream scoop or a large spoon, mound the meringue in 6 well-spaced mounds on the prepared baking sheet. Using the back of a spoon, form a depression in the center of each mound. Bake the meringues for 1 hour, turn off the oven and let them remain in the oven for 1 hour more. Remove the meringues from the oven and let cool to room temperature before serving. They may be stored in an airtight container at room temperature for up to 1 week.
In a large, nonreactive sauté pan over medium heat, bring the water and sugar to a boil, stirring to dissolve the sugar. Boil for 2 minutes to make a thin syrup. Add the plum slices and salt and return to a boil. Reduce the heat so the mixture simmers and cook until the plums are tender, 3 to 4 minutes. Add the butter and swirl the mixture in the pan until the butter is melted.
Arrange the meringues on individual plates. Spoon the plums along with some of the juice on top of the meringues. Serve the Pavlovas immediately. Serves 6.
